Abstract

The invention relates to the field of weld repairing equipment, in particular to equipment and method for repairing an in-service BOSS weld with defects. According to the main points of the technical scheme, the equipment comprises a support plate and support columns, wherein the support plate is provided with a clamping assembly capable of fixing the support plate to a main pipe; a horizontal rotating mechanism is arranged on the support columns; a transverse moving mechanism is arranged on the horizontal rotating mechanism; a vertical moving mechanism is arranged on the transverse moving mechanism; a gun rotating mechanism is arranged on the vertical moving mechanism; and a welding gun is arranged on the gun rotating mechanism. According to the equipment and the method, manual welding is replaced to repair the defects of the BOSS weld, thereby improving the repairing efficiency and improving the weld quality.

Description

technical field [0001] The present application relates to the field of weld repair equipment, in particular to a repair equipment and method for in-service BOSS welds containing defects. Background technique [0002] At present, there are a large number of BOSS welds in nuclear power plants under construction in my country, that is, there are defects such as slag inclusions and pores at the connection between the main pipe with the axis horizontal and the branch pipe with the vertical axis; During this period, manual welding was used for repairs; the method of repairing BOSS welds by manual welding was low in efficiency and unstable in quality, and welding operators were exposed to a large amount of radiation, which damaged their health. Contents of the invention [0003] In order to repair the defects of BOSS welds instead of manual welding, and then improve the repair efficiency and improve the quality of welds, the application provides a repair equipment and method for i...
